Exam 4: Manufacturing Materials and Processes

What is the process called that takes the compacted metal that has been removed from the die in the previous question and then heats it at temperatures below the melting point of the metal?

Describe the basic function of a laser device.

Name the manufacturing process that is commonly used to produce hollow products such as bottles, containers, recep- tacles, and boxes. This process works by blowing hot poly- mer against the internal surfaces of a hollow mold.

Name the material that is commonly used as a plastic for reinforced composites, also known as reinforced thermoset plastics (RTPs). Typical uses are for boat and recreational vehicle construction, automobiles, fishing rods, tanks, and other structural products.

What is another name for ultrasonic machining?

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -A00001 to A99999

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -P00001 to P99999

Given the gray cast iron material specification 30A, what does the prefix 30 denote?

Define surface texture.

Why are refractories used for such applications as furnace liners?

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -S00001 to S99999

Give the name of the manufacturing process that is gener- ally used to create products such as vinyl flooring, gaskets, and other sheet products. This process fabricates sheet or film thermoplastic or thermoset plastics by passing the ma- terial through a series of heated rollers. 59728_ch04_EOC_ptg01.indd 3 22/02/16 9:52 am

List at least two reasons why the mechanical drafter should be familiar with machining processes.

Describe the main function of a lathe.

Identify the alloying elements in bronze.

Describe the properties of aluminum.

List at least two advantages of using cores.

Name the material that has a wide range of makeup from liquid to solid. Liquid and semiliquid forms are used for lu- bricants. Harder forms are used where nonstick surfaces are required. Part 2: Manufacturing Processes

Give the name of the process that is similar to casting, but that uses a foam material that expands during the cure to fill the desired mold.

Identify at least four common uses for stainless steel.
